Digital BW, The Print

I use an Imacon Flextight regularly and have done tests on black and 
white negative scanning. My results are that scanning as a greyscale 
positive gets me the most efficient and tonally comprehensive scans, 
as another poster recommended. One important thing is to set the 
Texture/Unsharp masking sharpening setting to -120 or else the 
software will sharpen the image. This sharpening will increase grain 
presence in the image.
I sharpen later in PS using the Photokit sharpened plug-in.
The Imacon is a great machine.
Good luck with it.
